Exchange the RPC card to CEC enclosure I2C cable

Before you begin

Icon for electrostatic discharge wrist strapUse approved ESD procedures to prevent damage.

Attention:
  • This procedure is not a stand-alone procedure. Customer disruption and damage to the hardware might occur when microcode and power boundaries are not in the proper conditions for this service action.
  • If a serviceable event FRU repair directed you to this procedure, the microcode and power boundaries are already set.
  • If a serviceable event FRU repair did not direct you to this procedure, see MAP1230 Replace a FRU without using a serviceable event.
Notes:
  • All the cables and FRUs to be removed must be uniquely identified so they can be reinstalled correctly.
  • If an installed earthquake resistance kit prevents you from accessing this FRU, refer to MAP1600.

Remove the RPC card to CEC enclosure I2C cable

Procedure

  1. To locate this FRU, take one of the following actions and then return here and continue to replace the FRU:
    • If this FRU has a FRU identify indicator, use the FRU identify indicator, which is listed in MAP1240 Locating FRUs by using identify indicators. If not, use the location code.
      Note: There might be cases where the FRU failure or fencing conditions prevent the FRU LED indicator from being lit even if the FRU has power.
    • Use the location code, which is listed in MAP1245 Finding FRUs by using location codes.
    • If there is no FRU identify indicator or location code, you were sent here by an isolation MAP or symbolic FRU procedure. Use the information in that procedure and the figures in this procedure to locate the proper part to exchange.
  2. Most, but not all, FRUs have identify indicators. Use the flashing amber or solid blue FRU identify indicators to ensure that you are working on the correct enclosure or FRU.
  3. There are four I2C cables. See Table 1, Table 2, Figure 1, Figure 2, Figure 3, and Figure 4.

    Note: RPC end might be labeled "Cn-Pxx".

  4. To disconnect the I2C cable at the RPC card connector, squeeze the tab to release it. See Figure 1.
  5. For models 980 and 981, disconnect, the I2C cable at the CEC enclosure [P1-C8-T1 or P1-C8-T2]. See Figure 3 and Figure 4. For model 982, disconnect the I2C cable at the CEC enclosure [P1-C6-T1 or P1-C6-T2]. See Figure 2.
  6. Remove the cable retention hardware as needed and then remove the cable.

Procedure

  1. Route the cable.
  2. Connect the cable to the RPC card connector.
  3. Connect the cable to the CEC enclosure.
  4. Install the cable retention hardware.
  5. Exit this service information center parts exchange procedure and return to the procedure that sent you here.
